- The invention relates to apparatus .for

automatically measuring and -.delivei'ing 'milk'o'r otherliquid into bottles or: the like of the type-in Whichthemeasures arefittecl beneath a containing vessel or bowl and are each controlled andpermitted to .fillby'ian independent and positively operated inlet valve and are subsequently permittedto empty, by the pressureof the bottle mouth e opening the outlet valvejor engaging the m'echanism ofvalvesib'y which the liqu d is discharged from themeasurem v The, object of the invention 1s- -t0 provide measuring appliances which will operate correctly irrespective of the: liquidylevel in the container or milk bowl; and to provide means for the very rapid discharge. oft/he measures,xand the eva'ouationof the. air-and resulting froth from the" tops of the bottles in the measure as the latter empties, According; to the-inventionthe measures which dependvertically from :the bottom of the container orbowl, are constructed open atathe'top to theirfull areadirectly into the body of the containeranfd area fitgte'd with horizontally; operatinginlet slide valvesfwhioh slide on the bottom ofthe container over the opentops ofthe-measur'es and completely.- shutoff each measure when filled fro'm the residualliquid inthe bowl,

and also with outlet valves or cooks to o erate on the ,risingof' the bottleafterfthezinlet valves have been closed, to rapidly discharge the milk or liquid into the-bottles,- and to, evacuate theair' in" the bottles.

The fork bracket C and crank are preferably mounted in an oil bath B the bar co sliding in a bracket cw integral with orbolted to the wall of the oil bath B. When using the smaller measure of the crank is rotated in the direction" of the arrow Fig 1 and is reversed when using the larger measure 06 for the reason referred to hereafter. The crank or as it rotates engages the arms cu and at of the bracket C alternately moving the valve to and fro, completely uncovering and leaving the apertures to the measures completely open to the liquid in the bowl A. Owing to the angle of the arms on the bracket the valve remains stationary for a longer period when the measure is closed by it thenwhen open allowing the longer period for the measure to emptyand to fill the bottle for which reason the direction of'rotation of the crank or is reversed when. using the larger measure 06 from that when using the smaller measure. A snift pipe 02 is fitted to the valve 09 and extends above the liquor in the container A to admit air to the measure as the liquor flows out into the bottle.

In the form shown in Figs. 3 and 4 the measures 0.6 and of are each controlled by a separate slide valve the larger measure :6 by the valve dm and the smaller'measure of by the valve (Zn both'heldto the seats by 1 weight (if. g V are forked or slotted at 0370 and djto facilithe weight ch and reciprocated together. They are operated by mechanism comprising the forked bracket C and crank 07' similarto that described with reference to Fig. 1, but it will not require reversing to change fromfilling larger bottles to filling smaller bottlesit being only necessary to change the lifting. motion of the tables which raise the bottles; f I 1 j 1 In the'form shown in Figs. '5 and 6 the a slide valve cgover the inlet to the measures 0's and of is'similar to that shown in'Fig. 1 reciprocated b'y a lever de. I The slide valve operating mechanism is placed at the sideof the container A and is .drawn from below through a rodda'by the intermittent motion mechanism comprising the forked bracket C and crank 01 shown in Fig. 1. p In this construction a cranked lever do; dh is pivoted at die and the connecting-rod dais raised and lowered, thereby movin {the transverse spindle db bodily thereby reciprocating the sliding valve c'g'by therod de. The mechanism is balanced by the The lever dh andthe rod dc tate easy removal for cleaning;

The container A is shown with a cover and is provided with a float F to indicate the level of the milk therein. 1 i g In the form shown. inFig. the invention is applied to a rotary filling head with anumber of measures 06 of equal capacity adapted to fill bottles singly in rotation. The container A to which the measures are bolted is mounted on a central pillar A and over each measure the slide valve cg reciprocates to move backward to fill the measure and to move forward to close the measure as it approaches the position to fill the bottle. Each slide valve 0g is fitted as previously described with reference to Fig. 1 and motion is imparted to them by a stationary cam (1K through the lever CK and connecting rod CK. Each valve is fitted with a vent pipe. 1

Each measure 06, cf is fitted at its lower end with an outlet or discharge valve wliichis' opened to fill the bottle after the inlet slide valve has closed, either by con tact with the bottle mouth or by a connection with the bottle table.

As shown in Figs. 1 to 7 an outlet poppet valve P is preferred. The poppet valve P is of known construction and comprisesa tubular discharge member G fitted with a valve 9 engaging with a rubber seat 9?), a screwed abutment collar galat its lower end against which a spring pressesto close the valve and a rubber ring 96 against which the bottle mouth contacts to raise and open the valve 9. The valve may be fitted with a "rod or tube gf projecting upwards into the measure which may be readily machined in orderto obtain exact measure and also provided for easy removal of the valve. When tubular as in Fig. 7 it acts as a snift pipe to induce quicker flow of air and froth from the empty bottle, the snift pipe being provided with a non-return valve gg "of known construction to prevent leakage of liquid while filling the measure.

A float F may be placed in the container or the liquidin the container and permits as 7 .it fills all froth and air bubbles to rise and mingle with the milk in the container. And for cleaning purposes when the valves are removed each measure presents a perfectly clear barrel open at both ends thereof through which a brush or cloth can be passed for cleaning.

That I claim as my invention and desire toprote'ct by Letters Patent is t 1. A machine for filling bottles with a 'measured quantity of liquid comprising a bulk'container; a plurality of measures open at the top fitted to the bottom of and opening for their full area directly into the bodyof the container, a horizontally operating inlet slide valve adapted to slide to and fro over the tops of the measures, air escape pipesmounted on the slide valve, two

connecting rods controlling the slide valve,

a sliding bar coupled to the connecting rods, a forked'bracket on the sliding bar and a crank to reciprocate the sliding barto andv V 5 fro, and outlet valves at the lower end of of differing capacity from the first series also open at the top, fitted to the bottom of, and opening for their full areav directly into the body of the container, a horizontally operat- I ing inletslide valve adapted to slide to and fro over the tops of the measures, air escape pipes mounted on the slide valve, two

connectingrods controlling theslide valves,

v a sliding bar coupled to the connecting rods,

a forked bracket on the sliding bar vand a crank to reciprocate the sliding bar to and fro, and outlet valves at'the lower end of the measures tooperate on the rising of the bottles after the inlet valve has closed to rapidly discharge the liquid into thebot tles and evacuate air from the bottles.
